Description

  • The The invention relates to a sheet guiding device for a feeding region of a sheet-processing Machine, in particular a printing press.
  • at the feeder From sheet to sheet processing machines, it is common to have one suction delivery to use, which includes lifting and / or Schleppsauger. The separation The top bow of a pile is done by the lifting sucker suck in the bow in a lower position and then the Hubsauger be raised. While The bow is in a raised position, is separated from the stack trailing edge blown air led under the arch to separating the bow from the stack and lifting the bow support, while to maintain the air pressure lateral loosening blower continuously air against the stack side edges in the leading portion of the sheet blow. When the lifting suckers have reached their highest position, take over horizontally reciprocating conveyor suckers (drag suckers) the bow of the lifting suckers by sucking in the bow and the Suction air is switched off at the lifting suckers. Then transport the conveyor suckers processing the bow by a horizontal movement in the direction of the bow Machine, leaving the leading section of the sheet at a transfer point to sheet transport facilities of the downstream bow processing Machine, for example, over a feed table led Conveyor belts, arrives. The takeover by the sheet transport device of the sheet processing machine is done by clocked lowering of clock rollers, causing the bow on the circulating conveyor belts depressed becomes. Simultaneously with lowering the clock rollers is the suction air to the conveyor suckers interrupted and the conveyor suckers in their backward in sheet conveying direction Positioned. Thereby, that the bow on the transport way from the rear looseners moved, air increasingly reaches the top of the arch, which results in a flapping motion of the bow. This is the stable and reliable Transport of the lifted sheet, in particular in the area of the leading Bow area, on a given transport path to the bow-processing Machine and thus the machine processing on the machine cycle of the sheet coordinated arrival of the bow at the transfer point endangered. to solution This problem will sheet guiding devices above the Bogenförderweges used.
  • Such a sheet guiding device is known from the DE 17 86 232 A1 known. In the feed area of a sheet feeder, the sheet is guided on the sheet conveying path above the stack of sheets by a plurality of horizontally arranged, telescopically elongated Bogenleitstangen at its top. The telescopic rods extend from a in the sheet transport direction behind the suction head arranged transversely to the sheet transport direction, connected to the suction head Traverse above the sheet stack to the transfer point to a feed table of a printing press horizontally in a plane. In a format-dependent adjustment of the suction head in or against the sheet transport direction, the above sheet guide rods are pushed together. Through the tubular sections of the Bogenleitstangen form step-like sections. The guide elements are essentially dimensionally stable. A major disadvantage is that the sheet guiding elements must be maintained in order to maintain their functional reliability, since the telescopic rods are exposed to increasing wear due to contamination and abrasion.
  • By the DE 195 37 284 C1 It is known to use elastic or stretchable Leitbänder, which experience according to the travel of the suction head elongation or unwound by means provided spooling.
  • Of the Invention is based on the object, an alternative sheet guiding device to create the bows in the feed area sheet-processing machines, in particular printing machines, safe and damage-free leads and both on sheet length format as well as bow transverse format is adjustable.
  • The solution This object is solved by the features of claim 1.
  • One Advantage of the invention is that the sheet guiding elements not only in the longitudinal direction, but also in sheet transverse direction can be adjusted to format, so that the lateral format adjustment of facilities, such. B. lateral stacking stops or lateral relaxation blowers, is not hindered by the sheet guiding device and still a bowing over the entire sheet width takes place.
  • One Another advantage of the invention is that stepless guide devices be created with low friction.
  • In addition, the sheet guiding elements according to the invention have the advantage that they are extremely low maintenance, since due to blunt deflection for the strip material strong rope material can be used, which is correspondingly low wear is. Format differences from the largest to the smallest format in the paper length direction need not be compensated at the guide cords, as they have no fixed point on the suction head, but only deflected.
  • A embodiment The invention is illustrated in the figures and will be described below described.
  • It demonstrate:
  • 1 a sheet-fed rotary printing press in section in a schematic representation,
  • 2 a feeder of the printing press on average in a schematic representation with a sheet guiding system above the sheet stack,
  • 3 a plan view of the sheet stack with arranged over sheet guiding elements and
  • 4 an alternative embodiment for guiding the sheet guiding elements.
  • A bow 7 processing machine, z. B. a printing press 1 , indicates a feeder 2 , at least one printing unit 3 respectively. 4 and a boom 6 on. The bows 7 be from a sheet pile 8th taken and isolated or flaky about a feed table 9 a sheet feeder 27 fed to the bow 7 accelerates to the printing units 3 and 4 passes. These contain a plate cylinder in a known manner 11 . 12 , The plate cylinders 11 and 12 each have a device 13 . 14 for attaching flexible printing plates. In addition, every plate cylinder is 11 . 12 a device 16 . 17 assigned for semi or fully automatic plate change.
  • The sheet pile 8th lies on a controlled liftable stacking plate 10 on. The removal of the bow 7 takes place from the top of the sheet pile 8th by means of a so-called suction head 18 , which includes a number of lifting and towing suits 19 . 21 for singling the bow 7 having. In addition, blowing devices 22 for loosening the upper sheet layers and tactile elements 23 intended for stack tracking. To align the sheet pile 8th , especially the upper arch 7 of the sheet pile 8th are a number of side and rear stops 24 intended.
  • The suction head 18 is in the rear area above the sheet pile 8th arranged and slidably mounted in or against the sheet transport direction for format adaptation. At a common height level between suction head 18 and sheet stacking top are a number of flexible sheet guiding elements 26 , z. B. in the form of ropes, cords, belts, etc., which ensure that one of the blowing devices 22 can not leave the provided transport path with blown air sheet upwards. The sheet guiding elements 26 are with their first end 27 on a first crossbeam 28 fixed in the sheet transport direction in front of the sheet pile 8th is arranged, and with its second end 29 on a second crossbeam 31 attached to the sheet pile 8th is subordinate.
  • One on each of the rear crossbeams 28 arranged spring loaded tension pulley 32 is each a sheet guide 26 some embraced. Two pulleys 33 . 34 per sheet guiding element 26 are on levers 35 . 40 attached and directed downwards on the suction head 18 arranged that the sheet guiding elements 26 below and around the suction head 18 be guided around. The second end 29 each sheet guiding element 26 is by means of a height-adjustable and axially displaceable holder 36 at the second traverse 31 arranged. The holder 36 and the pulleys 33 . 34 are preferably arranged in height so that the sheet guiding elements 26 approximately in a common control plane E approximately parallel to the top of the sheet pile 8th or a conveying level lie.
  • If the suction head is used when processing small format lengths 18 in the sheet transport direction, ie in the direction of the second traverse 31 moved, so is a smaller geometric length of the constant length sheet guide elements 26 necessary. So that the sheet guiding elements 26 however, can be kept constantly tense, by the tensioner pulley 32 a small deflection of the sheet guiding elements 26 causes.
  • In a second embodiment according to 4 it is envisaged that the first pulley 33 by a combination of two S-shaped deflection pulleys 41 . 42 is replaced, wherein a pulley 42 on a spring-loaded lever 43 is arranged while the other pulley 41 stationary at the suction head 18 is arranged. Through this leadership of the sheet guiding elements 26 must be a travel of the suction head 18 can not be compensated.
  • The suction head 18 is in the rear area above the sheet pile 8th arranged and slidably mounted in or against the sheet transport direction for format adaptation. At a height level between suction head 18 and sheet stacking top are a number of flexible sheet guiding elements 26 , z. B. in the form of ropes, cords, ribbons, etc., provided, which ensure that one of the Blowing devices acted upon bow 7 can not leave the intended transport route upwards. The sheet guiding elements 26 are with their first end 27 on a first crossbeam 28 fixed in the sheet transport direction in front of the sheet pile 8th is arranged, and with its second end 29 on a second crossbeam 31 which the pile of sheets 8th is subordinate.
